Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551778, here are decompositions:

5 + 33551773 = 33551778
19 + 33551759 = 33551778
37 + 33551741 = 33551778
41 + 33551737 = 33551778
47 + 33551731 = 33551778
59 + 33551719 = 33551778
61 + 33551717 = 33551778
101 + 33551677 = 33551778

Showing the first eight; more decompositions exist.
